Lost my NOD32 key

Lasy year I bought NOD32 AV from a company called Simple Security Solutions here in Australia, the company is established in Qld. Anyhow a few days ago I re-formmated my laptop HDD and I'd forgotten to write down the username and password in the past as I installed it directly onto my laptop without writting it down.

I've been trying to get in contact with Simple Security Solutions but unfortunately no one is answering the phone.

All I need is for them to re-send me my username and password so I can download and re-install NOD32 on my laptop.

Sorry about this silly post but I don't know where I'm going wrong here. A few days ago I re-formatted my HDD to my Toshiba Satellite P200 notebook PC and after a full re-installation of Vista Ultimate and all other software, I decided to re-install NOD32. Now what I did I went to the Eset website and clicked on the version to download it asked me for a username and password before the download would commence. So anyhow I downloaded the program and installed it which all went well. Anyow when I went to update it re-asked me again for my username and password, why, I dont know.

My Q here is do I actually download the demo version of the version I mentioned above.

PS: I forgot to add, when I bought the sofware from a company here in Australia called Simple Security Solutions what I think I did was downloaded the demo verson, than onced I'd received my proper username and password from Simple Security Solutions, I re-entered the new username and password that was given to me, which allowed the demo version to change or become the full version.
